CORN HUSKER.

Application ledNovemberZS, 1.921, Serial No. 518,475. Renewed September 5,

To allwhomc'tma/concern:

Beit known that we, JosnPH SCHEMAN and LEONARD REINHART, citizens of the United States, residing at Courtland, in the county of Nicollet and State of Minnesota,

have invented certain new andusefullm-l provernents in Corn Huskers,of which the following. isa full, clear, and exact description. v Y

Our invention relates to corn huskers and has for its object to providesuch a devicev which removes the husk from `the corn, separates any loose grainsV of 'cornl'from the husks, and also loads the ears-of corn and any loose grains onto a `wagon or the like.

Another object of the inventionis to provide such a device which is simple `in construction and operation and which canbe manufactured at comparatively low cost.

A still further.y object of the invention is the provision of `novel means for agitating the corn husks as they come from the husking rolls in order to separate the loose grains of corn. K

Other objects and advantages of the invention will` be apparent from the following description when taken in connection with the accompanying drawings, in which,

Figure 1 Vis a side elevation of the complete machine. i 1

Figure 2 is a plan view of the husking rolls.

Figure 3 is a transve through the apparatus. A' Figure 4;is. a longitudinal vertical section through a portion of the machine.

Figure 5 is a plan view of the screen and related parts. t' i Figure 6 is a side elevation of the construction shown in Figure 5, and

Figure 7 is a detail view showing the screen operating mechanism,

Referring to the drawings more in detail, the numeral 1 designates the main frame of the apparatus which ismounted on the wheels 2. Mounted on the frame 1 is the hopper 3 which inclines downwardly from front to rear and is providedwith a convever or elevator 4 which carries the corn touthe forward part of the hopper Where it is dropped onto husking rolls to be later described. The elevator 4 comprises an endless belt 5 carried by rollers 6 and 7. Roller 7 is provided with a sprocket wheel 8 b y means ot which the elevator or conveyer is operated. Mounted below the hopper 3 are rse `vertical section 1922. `Serial No. 586,363.

the-husking rolls 9 and 10, the roll 9 being formed with the spiral knives 11, and the rolllOfwiththe pins 12. The rolls 9 and 10 are inclined downwardly from front to rear and have their ends mounted in suitable bearings 13 and 14. vThe rolllO is yieldinglyheld in cooperative relation with the roll 9 by meansl of coil springs 15, thereby preventing' damage to the rolls in the event of some hard object getting between the rolls.- Roll'9 is operated by means of the bevelgear 16 mounted on one end thereof and which isv in mesh with the bevel gear 17 carried on shaft 18. The opposite ends of the rolls 9 and 10 are provided'with the meshing gears 19 and 20 whereby the roll 10 is operated. Shaft 18 is driven by means of the pulley 21 and belt 22 which are in turn driven by the motor 23.

Slidably mounted on the upwardly ek-4 tending fraine 24 is the sieve or screening device 25 which is further supported by the links or chains 26. The screen 25 is reciprocated along the frame 24 by means of the adjustable arm 27 which is strapped to the eccentric 23 on shaft 29.` paddle or agitator 30 is pivotally mounted on the screen 25, and spaced slightly therefrom.4 of oscillating the paddle 30, a link 31 is provided; the link being pivotally attached at one end to the body frame (Fig. 1), andat the other end being pivotally attached to thepaddle. Itis thus obvious thatas the screen is reciprocated the paddle will be 0scillated. v

The frame 24 is provided with rollers 32 and `33 at opposite ends thereof, and by means of these rollers the endless conveyer 34 is operated; roller 32 being provided with a sprocket 35 with which the chain 36 meshes for this purpose. Chain 36 also meshes with sprockets 8, 181329, 35 and guide roller 37 in order to transmit power to the respective shafts of the apparatus.

ln operation, the corn is thrown onto the elevator 4 which carries it forwardly and upwardly and drops it on to the hue-king rolls 9 and 10, `1n traveling along these rolls the husk is removed from the ears of corn by means of the knives 11 and pins 12, and

lthe ears are deposited on the conveyer 34 and For the purpose of the paddle cause the grains of corn to pass through the perforations `ofthe screen and onto the conveyer 34. i

From the foregoing descriptionvit will be seen that Iwe have provided a power driven machine which requires practically no attention other than the placing of the corn in the Vhopper 3, and further that the various lparts of the machine are composed of as few elementsgas areconsistentwith the reliable performance of the work required. 4

' Inaccordance with the patentstatutes we have :described what-we now believe to be theibest embodiment of the invention, but wev do not wish to'be understood thereby as limiting ourselves or ythe Scope oi the invention, as many changes and modifications Hiyayfbemade without i, departing 'from the spirit ofthe invention, all such we aim to include in the scope ofi-the appended claims. fWhat we claim `asnew and `desire to secureby.
